Mystery Dungeon Red and Blue Rescue Team

An announcer asks as a Totodile wakes up in first person "What if you woke up one day," the Totodile inspects its hands as the announcer says this, saying "whoa" in the process. It then proceeds to go over to the lake to inspect its face and the anouncer continues, "and you were a pokemon?" Totodile then gives a shocked expression with a more enthusiastic "whoa!"
The commercial then cuts to game footage

PokéPark Wii: Pikachu's Adventure!

A commercial for the game shows Pikachu and some others standing near a hole. However, the others accidentally push Pikachu into the hole, and a Mew appears. Pikachu falls to the ground beneath the hole, and begins running with a Ponyta, jumping on a ski lift, running through a chilly town, performing with a Mr. Mime, talking to a Croagunk and Shaymin, dancing with a Venusaur and Buneary, and racing against others. The commercial then shifts to an Empoleon surfing and a Pelipper flying. Pikachu then reappears on a Lapras and with a Drifblim flying off into the horizon to finish off the commercial. Another commercial with different scenes was also aired in the United States.

Anime

Commercials were also formerly made for anime episodes, but they have stopped being produced in the US. From time to time, Pokémon marathons aired on Cartoon Network will be given a commercial. Currently, commercials on Saturday's new episode time slots have Pokémon mentioned in it.
